다양한 모터에 있어서 기본적으로 고정자와 회전자의 구조는 동일하다. 그러나 고정자와 회전자 사이의 상호 작용으로 회전자가 회전하는 원리에 따라 모터의 종류가 나뉘게 된다. 그리고 고정자 코일에 인가되는 전원의 종류나 상에 따라 모터의 종류가 나뉘기도 한다. 또한, 고정자 코일이 와인딩된 방법에 따라 모터의 종류가 나뉘기도 한다.The stator and rotor are basically the same in the various motors. However, due to the interaction between the stator and the rotor, the type of motor is divided according to the principle of the rotation of the rotor. The type of motor may be divided according to the type or phase of power applied to the stator coil. In addition, the type of motor may be divided depending on how the stator coil is wound.
먼저, 도 1 내지 도 2를 참조하여 종래 모터에 대해서 상세히 설명한다.First, a conventional motor will be described in detail with reference to FIGS. 1 and 2.
도 1에 도시된 바와 같이 고정자(1)는 고정자 코어(2), 상기 고정자 코어의 원주를 따라 복수 개 형성되는 티스(3), 고정자 코어와 티스의 상하부에 각각 삽입되어 고정자 코일(6)이 와인딩되는 상하 인슐레이터(4, 5)를 포함하여 이루어진다.As shown in FIG. 1, the stator 1 includes a stator core 2, a plurality of teeth 3 formed along the circumference of the stator core, and a stator coil 6 inserted into upper and lower portions of the stator core and the teeth, respectively. It comprises a vertical insulator (4, 5) is wound.
그리고 상기 고정자(1)의 내부에는 회전자(미도시)가 회전축(미도시)과 연결된 상태로 위치되며, 상기 고정자의 상부에 피씨비(60)가 고정된다. 즉, 상기 피씨비에 형성된 홀(61)에 상기 고정자의 상부에 형성된 고정돌기(22)가 삽입되어 상기 피씨비(60)가 고정된다.In addition, a rotor (not shown) is positioned inside the stator 1 in a state of being connected to a rotating shaft (not shown), and the PC 60 is fixed to the top of the stator. That is, the fixing projection 22 formed in the upper part of the stator is inserted into the hole 61 formed in the PCB to fix the PC 60.
이 후, 상기 고정자(1), 회전자, 그리고 피씨비(60)가 브라켓(70) 내부에 수용된다. 한편, 상기 회전축과 상기 회전자는 상기 브라켓에 고정된 베어링(미도시)에 의해 회전 가능하게 지지가 된다.Thereafter, the stator 1, the rotor, and the PCB 60 are accommodated in the bracket 70. On the other hand, the rotating shaft and the rotor is rotatably supported by a bearing (not shown) fixed to the bracket.
도 1과 도 2에는 티스(3)가 9개 형성되어 있으며 각각의 티스에 고정자 코일(6)이 와인딩되어 집중권 형태로 고정자 코일이 와인딩된 형태가 도시되어 있다. 여기서, 도 2는 도 1에 도시된 고정자 외주면의 전개도이다. 그리고 고정자 코일에 3 상(u, v, w)의 전원이 공급되며 120°간격으로 각 상의 고정자 코일(6)이 와인딩된 형태가 도시되어 있다. 이러한 형태의 고정자에 있어서 종래의 고정자 코일 와인딩 방법을 설명하면 다음과 같다.In FIG. 1 and FIG. 2, nine teeth 3 are formed, and the stator coils 6 are wound around each of the teeth, and the stator coils are wound in a concentrated winding form. 2 is an exploded view of the outer circumferential surface of the stator illustrated in FIG. 1. The stator coils are supplied with power of three phases (u, v, w) and the stator coils 6 are wound around each phase at 120 ° intervals. In the stator of this type, a conventional stator coil winding method is described as follows.
먼저, u 상의 고정자 코일(7)이 1번 티스에 시계방향(화살표 방향)으로 와인딩된다. 물론, 반드시 시계방향으로 와인딩될 필요는 없고, 어느 경우나 각 상의 고정자 코일이 동일한 방향으로 와인딩되기만 하면 된다.First, the stator coil 7 on u is wound clockwise (arrow direction) at one tooth. Of course, it does not necessarily have to be clocked in the clockwise direction, in which case the stator coils of each phase need only be wound in the same direction.
와인딩이 끝나면 인슐레이터(4)에 형성된 홈(10)을 통하여 u 상 고정자 코일의 연결선(12)이 인슐레이터의 외부로 빠져나오게 된다. 그리고 연결선의 위치를 결정하는 돌기(11)에 연결선의 일단이 고정된 상태에서 인슐레이터의 외주면을 따라 연결선이 연장된다. 상기 연장된 연결선(12)은 다시 인슐레이터에 형성된 홈(10)을 통하여 인슐레이터 내부로 삽입되고, 4번 티스에 다시 시계방향으로 와인딩된다. 같은 방법으로 연결선(12)이 위치되며, 7번 티스에 다시 시계방향으로 와인딩되어 고정자 코일의 말단은 중성점(N)을 형성하게 된다.After the winding is finished, the connecting line 12 of the u-phase stator coils comes out of the insulator through the groove 10 formed in the insulator 4. The connection line extends along the outer circumferential surface of the insulator in a state where one end of the connection line is fixed to the protrusion 11 for determining the position of the connection line. The extended connection line 12 is inserted into the insulator again through the groove 10 formed in the insulator, and is wound clockwise again at the fourth tooth. In the same way, the connecting line 12 is positioned and wound clockwise again to the seventh tooth so that the end of the stator coil forms a neutral point (N).
여기서, u 상의 고정자 코일(7)은 두 개의 연결선(12)을 갖게 되며, 양자는 높이가 서로 다르도록 위치되며, 이러한 위치의 조정은 다양한 높이에 형성된 돌기(11)에 의해서 이루어진다.Here, the stator coil 7 on u has two connecting lines 12, both of which are positioned so that the heights are different from each other, and the adjustment of this position is made by the projections 11 formed at various heights.
이 후, v 상의 고정자 코일(8)은 2번 티스, 5번 티스, 그리고 8번 티스에 와인딩되며, w 상의 고정자 코일은 3번 티스, 6번 티스, 그리고 9번 티스에 와인딩된다. 여기서, 상기 v 상의 고정자 코일은 두 개의 연결선(13)을 갖고, w 상의 고정자 코일(9)도 두 개의 연결선(14)을 갖는다. 그리고 이들 연결선들의 높이는 서로 다르게 위치된다.The stator coils 8 on v are then wound at 2, 5 and 8 teeth, and the stator coils on w are wound at 3, 6 and 9 teeth. Here, the stator coil on v has two connecting lines 13, and the stator coil 9 on w also has two connecting lines 14. And the height of these connecting lines are positioned differently.
여기서, u, v, w 상의 고정자 코일의 시작단은 각각 대응되는 전원과 연결되며, 각 고정자 코일의 말단은 서로연결되어 중성점(N)을 형성하게 된다.Here, start ends of the stator coils on u, v, and w are respectively connected to a corresponding power source, and ends of each stator coil are connected to each other to form a neutral point (N).
한편, 도 2에 도시된 바와 같이 각 상의 고정자 코일의 연결선(12, 13, 14)은 서로 절연 거리가 확보되도록 위치되어야 한다. 따라서, 이러한 연결선들은 서로 다른 높이를 갖도록 위치되어야 하며, 이를 위해서 인슐레이터(4)의 외주면을 따라 서로 다른 높이를 갖는 돌기(11)들이 형성되어야 했다.On the other hand, as shown in Figure 2, the connection lines 12, 13, 14 of the stator coils of each phase should be positioned to ensure an insulating distance from each other. Therefore, these connecting lines should be positioned to have different heights, and for this purpose, protrusions 11 having different heights should be formed along the outer circumferential surface of the insulator 4.
또한, 이러한 연결선들이 인슐레이터의 상부, 즉 상부 인슐레이터(4)에만 위치되므로 이러한 연결선들의 높이의차이를 두기 위해서 돌기(11)들의 형성된 높이도 다양하게 형성되어야 하며, 따라서 인슐레이터의 높이가 높아지는 문제가 발생하였다. 물론, 도 1과 도 2에 도시된 바와 같이 다양한 높이를 갖는 돌기(11)들이 형성되어야 하므로 인슐레이터 제작을 위한 금형이 복잡해지고, 이로 인하여 원가가 상승되는 문제도 있다.In addition, since the connecting lines are located only on the upper part of the insulator, that is, the upper insulator 4, the heights of the protrusions 11 must also be formed in various ways in order to make a difference in the heights of the connecting lines, thus increasing the height of the insulator. It was. Of course, since the protrusions 11 having various heights must be formed as shown in FIGS. 1 and 2, the mold for manufacturing the insulator is complicated, and thus, the cost increases.
아울러, 한 상의 연결선들이라고 하더라도 서로 높이가 다르게 위치되므로 와인딩 불량이 발생할 우려가 높으며, 연결선들 간에 충분한 절연 거리가 확보되지 못할 우려가 있었다.In addition, even if the connection wires of the one phase is different from each other because the height of the winding failure is likely to occur, there was a fear that a sufficient insulation distance between the connection lines can not be secured.
한편, 종래에는 고정자 상부에 피씨비(60)가 위치되는 경우에 고정자 코일의 시작단(7', 8', 9')은 직접 피씨비에 솔더링되어 제조 공정이 복잡하고, 오결선 우려가 많았다. 그리고, 상기 고정자 코일의 시작단(7', 8', 9')은 고정자(1)의 인슐레이터(4)와 피씨비(60) 사이의 간극으로 빠져나와 피씨비 상에 솔더링이 이루어졌다. 왜냐하면 피씨비 내측에 고정자 코일의 시작단이 위치하는 경우 회전축과의 간섭 우려가 있기 때문이다.On the other hand, in the past, when the PC 60 is positioned above the stator, the start ends 7 ', 8', and 9 'of the stator coils are directly soldered to the PC, so that the manufacturing process is complicated and there is a lot of erroneous wiring. The start ends 7 ', 8', and 9 'of the stator coils are pulled out into the gap between the insulator 4 and the PC 60 of the stator 1, and soldered onto the PC. This is because there is a risk of interference with the rotating shaft when the start end of the stator coil is located inside the PCB.
따라서, 결국 상기 고정자 코일의 시작단(7', 8', 9')은 고정자(1)와 브라켓(70) 내측 사이에 위치되어 상기 브라켓과의 절연이 유지되지 않을 우려가 있었다. 왜냐하면, 일반적으로 상기 고정자 코어(2)는 브라켓(70) 내측에 압입되어 고정되어, 상기 브라켓 내측벽과 상기 고정자의 인슐레이터(4) 사이와의 간격은 매우 좁게 형성되기 때문이다.Therefore, the start ends 7 ', 8', 9 'of the stator coils are located between the stator 1 and the inside of the bracket 70, so that the insulation from the bracket may not be maintained. This is because, in general, the stator core 2 is press-fitted into the bracket 70 and fixed, so that the distance between the bracket inner wall and the stator insulator 4 is very narrow.
그리고, 고정자 코일의 말단들이 형성하는 중성점을 고정하기 위하여 절연 튜브(미도시)와 랜싱사(미도시)를 이용하여야 하므로 제조 공정이 복잡하였다. 또한 이러한 중성점은 인슐레이터(4)의 외면에 고정되므로 상기 중성점과 상기 브라켓 사이의 절연 불량이 발생될 우려가 있었다.In addition, in order to fix the neutral point formed by the ends of the stator coils, an insulation tube (not shown) and a lancing yarn (not shown) must be used, which makes the manufacturing process complicated. In addition, since the neutral point is fixed to the outer surface of the insulator 4, there is a fear that insulation failure between the neutral point and the bracket may occur.
상기 문제점을 해결하기 위하여 본 발명은 코일부의 접지코일과 3상의 코일이 각각 연결되어지는 커넥터부를 상기 코일부의 상측에 결합하여 자동으로 상기 코일들을 연결하도록 하며, 상기 커넥터부의 각 전극 간을 별도의 케이블로 자동으로 연결하는 것을 특징으로 하는 3상 모터 와인딩 자동화를 위한 커넥팅 몰딩을 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention couples the connector part to which the ground coil and the three-phase coil of the coil part are respectively connected to the upper part of the coil part to automatically connect the coils, and separately between the electrodes of the connector part.
